[AA] getExpectForActual analysis-api now returns compatible or weakly incompatible

^KTIJ-27522 Fixed

It's the only reasonable behavior for this API in it's current shape
(when it returns a list of declarations)

It's a common mistake to take only Compatible from
expectActualMatchingMap. The problem will be gone after I fix KT-62590

Motivation to fix this bug, is because it will be easier for me to split
expect-actual matcher-checker-monster thing KT-62590
